Giant structure discovered deep beneath Bermuda is unlike anything else on Earth

Scientists have discovered an unprecedented 12.4-mile-thick rock layer beneath Bermuda's oceanic crust, unlike anything found elsewhere on Earth. This dense layer may explain why Bermuda sits on an elevated oceanic swell despite no volcanic activity for 31 million years, when such swells typically subside without active hotspots. The discovery suggests leftover volcanic material from ancient eruptions continues supporting the island's unusual elevation in the Atlantic Ocean.
